Abstract
This invention relates to a process for the separation of a metal complex catalyst and any free ligand which may be present, from a homogeneous organic synthesis reaction mixture using sub-nanoporous, chemically stable membranes having discrete pores which allow organic products and by-products to pass through the membrane as permeate while retaining substantially all of the metal complex catalyst and free ligand, if any, as retentate.
